The DataStax agent requires exec permissions to the JDK tmpdir. Map to a different executable directory before mounting
the tmp directory with the noexec flag. If the tmp directory has the noexec flag set, the agent cannot start.

Agent Heap Size

For most environments, the DataStax agent will require 1GB of heap. If an agent is
experiencing OutOfMemory issues, try changing the -Xmx property in
datastax-agent-env.sh to 2048M (-Xmx2048M). If
issues still persist, please contact DataStax Support so DataStax can determine whether
your environment requires even more heap or if there is an issue in the agent.
